SPECIFICATION forming part of Letters Patent No. 580,636, dated April13, 1897.

Application filed February 4, 1896. Serial No. 578,044. (No model.)Patented in England November 12, 1894, No. 21,811.

To @ZZ whom it may concern:

Beit known that We, TAYLOR BURRows, engineer, of 88 Upper KenningtonLane, and DICK EDWARDS RADCLYFFE, horticultural decorator, of 56Gloucester Crescent, Regents Park, London, England, subjects of theQueen of Great Britain, have invented Improvements Relating to theSpinning of Ramie, Rhea, China-Grass, or other Fibers, (for which wehave Obtained Letters Patent in Great Britain, No, 21,811, datedNovember l2, 1894,) of which the following is a speeication.

Heretofore in spinningframes used for bers, such as rhea, china-grass,or ramie, Wool, silk-waste, aX, hemp, and jute, the roving is fedthrough slowly-revolvin g rollers and carried forward to drawing-rollerswhich move quicker than the retaining-rollers and so draw the bers ofwhich the roving is composed, which is twistedby the spindle and Woundon the spool or bobbin. There is a slight twist in the roving, andvarious devices are in use to prevent the iibers being drawn awayirregularly from the roving by keeping the twist in the said roving, andfor this purpose in flax, hemp, and jute spinning on the dry frame theroving is made to pass over and against a friction-plate, while inwooland silk-waste spinning the roving is carried forward from the back tothe front drawingroller over two or three carrier-rollers having a lighttop roller pressing on the roving. These various modes of spinning 'asheretofore do not leave the thread or yarn very smooth or even on thesurface thereof, but, on the contrary, same remain more or less hairy,which is an objection, especially where brilliancy is desired.

N ow the object of our present invention is primarily to spinchina-grass, rhea, or ramie (although other bers to which our inventionis applicable may also be similarly spun) wet, so that the yarn we thusproduce will be very smooth and even on its surface and having manyadvantages, particularly in the case of china-grass, rhea, or ramie,whenthus spun; and in order to fully explain our present invention wewill proceed to describe same with reference to the drawings hereuntoannexed.

Figure l is a diagrammatic side view showing our improvements.v Fig. v2is a front view-. e., looking in the direction of the arrow z.

According to this invention we pass the roving A, as same comes from thebobbin B on the spinning-frame, through a trough, bath, or vessel C, ofany suitable shape, mounted in the spinning-frame and containing liquid,for instance, pure water (hot or cold) or any suitable chemical oringredient, therein or any other suitable liquid mixture or solution towet or moisten the ber and add to its brilliancy and also, if desired,to tint or dye it or otherwise treat it during spinning.

The roving is caused to pass under a rod,

roller, or rail D or other guide in said trough or vessel C to insureimmersion in said bath, and thence is passed between the back or feedrollers E and is carried on over carrier-rollers F G H, having V-shapedcircumferential grooves Jtherein, F' G H, respectively, according to`our present invention, in the bottom of which grooves the rovingsrespectively lie. These carrier-rollers (two, three, or any suitablenumber of which may be used, for instance, three rollers, such as F G H)are mounted slightly higher than ('12. e., slightly above) the directstraight line between the back or feed rollers E, and thedrawing-rollers are advantageously in the form of a curve or arch,whereby the strain put on the roving by the drawing-rollers forces ordraws the roving down to the narrowmost bottom part of the said V-shapedgroove, and thereby the roving is, as it were, wedged therein, andconsequently any untwisting of the roving is prevented or practicallyprevented, while at same time the rovings can freely run (in the saidV-grooves) over said carrier-rollers F, G` and H, which latter may bemechanically revolved at 'the same or dierent peripheral speed as thefeed-rollers, or said V-grooved carrier-rollers may be idle-rollers. Bythis means also we dispense with the use or necessity of top rollersover the carrier-rollers F, G, and H.

The drawing-rollers operate as heretofore to draw away the ber in thiswet state and same is then twisted into a thread or yarn and wound onthe bobbins in the usual or any suitable manner.

IOO

Having thus described ourinvention, what a liquid bath disposed betweensaid bobbinwe claim as new, and desire to secure by Letters Patent ofthe United States, is-

l. In a spinning-machine, the combination of a bobbin-support,feed-rolls, a holder for a liquid bath disposed between saidbobbinsupport and feed-rolls, drawing-rolls, and a series ofCarrier-rolls disposed on a convex are between the feed-rolls and thedrawingrolls.

2. In a spinning-machine, the combination of 2t bobbin-support,feed-rolls, at holder for support and feed-rolls, drawingmolls, and eseries of carrier-rolls disposed on a convex arc between the feedandvdraw rolls and provided with V-shaped peripheral grooves in whichthe roving is wedged during its passage whereby untwisting thereof isprevented.
